The Benefits of Sunlight


It is well known that there are many benefits of exposure to sunlight for humans. When the sun’s UVB rays hit people’s skin, this creates a trigger that tells the body to produce vitamin D. Vitamin D is widely referred to as the sunshine vitamin, and this boosts overall health, improves brain function, protects people against certain types of cancer and protects against inflammation.

Sunlight can directly affect the skin, and give positive improvements for people with skin disorders like acne, eczema and psoriasis. When the sun’s rays hit the skin, white blood cells increase, and this helps the immune system to defend and fight against many types of infection.

Another benefit of sunlight on the human body is that it lowers blood pressure in people who have high blood pressure. The sun’s rays also increase the oxygen content in blood, and this improves the body’s capability of delivering oxygen to tissues, having a similar effect as exercise on the body’s muscles.

One of the best known benefits of sunlight is that it cures a form of depression known as seasonal affective disorder (SAD). This disorder is common in the winter months, but is also common with people who work for long hours indoors at any time of the year.

Indoor Lighting Using Sunlight

While spending long hours indoors, and a working life indoors, is inevitable for many, there are very clever ways of enjoying the benefits of sunlight while indoors. Indoor lighting directly from sunlight is one such solution.

Sun collectors can be positioned on the roofs of buildings, and this light can be transported over fibre optic cables into light projectors inside any building. This means that people who are indoors can work under sunlight, and enjoy the health benefits of sunlight, even when indoors.
